Abstract

The desulfurizative oxidation of 1,2-dithiole-3-thiones with various oxidizing reagents was reexamined using 4,5-benzo-3-selenoxo-1,2-dithiole as a typical substrate. The product thus obtained was 4,5-benzo-1,2-thiaselenole-3-one, but not an expected 4,5-benzo-1,2-dithiole-3-one. The reaction pathway via a selenine1 is postulated.
